it appears that the SEO optimum is "repeat common search terms but in natural language" and so now every google result for thing like "fix coil whine" or "toilet not filling" are FAQ style posts by domains you've never heard that are like:
How to fix coil whine?
What causes coil whine?
Can coil whine cause damage?
the search situation is dire because sure "toilet not filling" doesn't tend to have misinformation, but if any schmuck can register a 4 dollar domain and get gpt2 to blast out some misinfo that the google algo loves and make bank on advertising (also sold by google) then how am I supposed to trust google when I ask it about things that tend to have common misconceptions or falsehoods like pest remedies or medical symptoms?
@SuricrasiaOnline DDG just uses Bing for search data, but the ! searches make it actually useful despite that.
